Bonwill’s Triangle in Greek Human Mandibles

Abstract

In 1858 an American dentist, G Bonwill described an equilateral triangle, which was the basis for Bonwill’s theory of occlusion. The equilateral triangle had 100mm [4inches] formed by lines joining the medial contact point of the incisors and the centers of the mandibular condyles [1,2]. Bonwill based this theory on measurements of 6.000 skulls and 4.000 living persons [3]. A literature review shows that the ideal arch is considered to be symmetrical.
